Try to improve your channel first and read all the stickies here in the strategy forum. You have only made 3 videos so far, the video's are spaced out too far in between and you can improve lots of other things as well before thinking of how to get noticed. First work on the content so that when people do notice you, they stick around.
There is no magic unfortunately, only hard work and patience. You have to compete with all the other channels out there and even if you do everything right, you're looking at half a year to a year at least to become somewhat popular, posting every day high quality videos.
